FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60512-7-1 has been prepared by subcommittee 48B: Connectors,

of IEC technical committee 48: Electromechanical components and mechanical structures for

electronic equipment.

This standard cancels and replaces Test 7a of IEC 60512-5, issued in 1992. The structure of

IEC 60512 series is explained in IEC 60512-1-100.

The text of this standard is based on the following documents:

CDV Report on voting

48B/2016/CDV 48B/2107/RVC

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

CONNECTORS FOR ELECTRONIC EQUIPMENT –

TESTS AND MEASUREMENTS –

Part 7-1: Impact tests (free connectors) –

Test 7a: Free fall (repeated)

1 Scope and object

This part of IEC 60512, when required by the detail specification, is used for testing

connectors within the scope of technical committee 48. It may also be used for similar devices

when specified in a detail specification.

The object of this standard is to define a standard test method to assess the ability of a

connector to withstand the impacts it would receive when dropped repeatedly.

2 Normative

references

The following referenced documents are indispensable for the application of this document.

For dated references, only the edition cited applies. For undated references, the latest edition

of the referenced document (including any amendments) applies.

IEC 60512-1-1,

Connectors for electronic equipment – Tests and measurements – Part 1-1:

General examination, Test 1a: Visual examination

ISO 48:2007,

Rubber, vulcanized or thermoplastic – Determination of hardness (hardness

between 10 IRHD and 100 IRHD)

3 Preparation of the specimen

Unless otherwise specified, the specimen shall not be mounted or wired, but shall be fitted

with normal accessories (e.g. hoods, cable glands) according to the detail specification.

4 Test

method

The test shall be executed by means of a rotating barrel as described in Clause 5. During a

test not more than one sample shall be present in the barrel.

The barrel turns at a rate of approximately 5 rev/min.

The total number of revolutions (the number of falls is twice the number of revolutions) shall

be according to the detail specification.

NOTE (Detail) specifications may define different numbers of revolutions for specimens with a different mass.

5 Test

equipment

The specimen shall be tested in a tumbling barrel as shown in Figure 1.

Where a large number of specimens has to be tested, the barrel may contain a number of

sections, one specimen being placed in each section, so that simultaneous testing may be

carried out.

The width of each section, W, is not specified but should preferably be between 200 mm and

300 mm, depending on the size of the specimen.

Each compartment in which the specimen rests between falls is backed by a wedge-shaped

piece made of chip resistant rubber with a hardness of 80

±

20 IRHD, as defined in ISO 48,

and the sliding surfaces of that same compartment are made of smooth, hard plastics

laminated sheet.

The rotating barrel is designed so that the shaft does not protrude into the interior.

The rotating barrel is provided with an aperture with a lid which may be made of transparent

acrylic material.
